SFA's ResNet FAQ

Can I use a modem and the Ethernet on the same computer?
Yes, provided that both the modem and Ethernet card have each been installed and configured properly. A modem can be beneficial for uses other than Internet connectivity such as providing voice mail and fax machine functionality (with the appropriate software). A modem can also provide an alternate means of Internet connectivity if the computer is moved to a location where an Ethernet connection is not available—very common with laptops and other portable computers. (See question 7 for additional information on dial-up access.) However, there should never be a circumstance where you will need to use both simultaneously in order to obtain Internet connectivity.
